Intruder :
the Pilot MUST:[...]
Query ATC as to whether they have the traffic and are aware of the conflict. For example: "Center, ABC123, I have a TCAS TA for co-altitude traffic 20 miles ahead. Do you have them?"
If you want to get yourself in trouble, it is a good advice.
You are going to upset a lot of people down there .
I would also avoid to use the word " must" in here . There are existing ACAS procedures , and so far those MUST be followed. The rest is only our humble opinion, mine included.
